class_docstr: Adds the node degree as one hot encodings to the node features
  (functional name: :obj:`one_hot_degree`).
  
  Args:
      max_degree (int): Maximum degree.
      in_degree (bool, optional): If set to :obj:`True`, will compute the
          in-degree of nodes instead of the out-degree.
          (default: :obj:`False`)
      cat (bool, optional): Concat node degrees to node features instead
          of replacing them. (default: :obj:`True`)

      return f"{self.__class__.__name__}({self.max_degree})"
